FWIW this was born out of the fire code as a hedge against exposure fires from grilling, primarily, probably patio heaters and what not as well now. It then migrated into 13R due to the near universal pairing of IBC/IFC with 13R. IFC/IFC commentary unfortunately doesn't give a ton of wiggle either. One could argue it's a continuation of a building feature in the case of the building overhang, and not a unique "roof or deck" for the patio/balcony in the case you point out. I would say in any case where the construction is non-typical and exclusive to t he balcony/porch that you'd for sure want to be protecting it if you're doing 13R in a Type V building. I've actually had to argue with AHJs who don't follow the "if this then that" of the IBC and want to apply this requirement for 13 systems (which it clearly spells out isn't required because the exposure protection of the space above is provided EG attic protection).

Sent by: "Sprinklerforum" <[email protected]> BE ADVISED - This email originated outside EMCOR. I notice that 13R https://urldefense.com/v3/__http://6.6.5.1__;!!FaxH778!LZEG720xa9QB8flV1k4h_DvtEa5mpY9d1Tb-yl7hCCYoFO9c5UQJaWjgqpQhbEab$ (2013 ed) requirement for sprinkler coverage for exterior balconies does not have a depth requirement unlike the 4ft rule found in 13. I have some apartments I'm bidding with a balcony at the upper level and the overhang is 3 ft.over the balcony. I'm going to put sprinklers covering the overhang for bidding purposes but let's say this is just a typical roof overhang like you would have on a single family home of about 12" - 24", with the current wording of 13R it sounds like you would have to sprinkler it no matter what - even 8" or whatever. Is that actually the case or can we make the distinction between an overhang and a "roof" - which is actually the terminology that 13R uses. "Roof" to me means something covering the entire footprint of the balcony and not an overhang covering only a small portion. Any thoughts or clarification?
